David Kremelberg saved me in my time of dissertation crisis! I had completed most of my dissertation, but needed expert consultation for the results of my quantitative analysis in SPSS. While I am extremely proficient in most areas of my terminal degree, statistics continue to frustrate and confuse me. David provided an excellent review of my results in a very professional writing style. The work he provided was exactly what I had requested in an extremely quick turnaround time. When I found David's website on the internet, I was a little reticent to use a professional that I had not researched well and I did not know, but those fears were completely unfounded. David is very responsive, provides specifically what you request, and is also very professional. 5 Stars plus!
